Abstract

The present invention provides a process for making uniform carbon-coated LiMPO4 powders for use as a cathode material in lithium ion batteries. In one embodiment, the process comprises synthesizing a LiMPO4 powder. The process further comprises coating a carbonaceous coating on to the LiMPO4 powder to form a coated LiMPO4 powder. Additionally, the process comprises carbonizing the coated LiMPO4 powder.
